it is said that problems with the UEFA are going on and they could even be excluded from that competition as well.
Juventus are threatened by sanctions and this was the main factor of their bad performance at least in some games. This reason might make other players hesitate a lot before joining Juventus but if they were excluded from European competitions then for sure this will reduce the names willing to come to Turin.
AFAIK Juve is trying to let many players go and recruit others. Hopefully this will not be a hard job..
But I think they are screwed already even if the UEFA does not decide to exclude them from European competitions because which top player would go to Juventus Turin when they are only qualified for the Conference League? The threat that even more could happen and they might be excluded for another season makes the situation even worse, but I think it almost as bad as it can get no matter whether they play the Conference League or not. If a superstar is used to play the Champions League, going down into the Europa League is hard already (for Liverpool for example), but going to the Conference League is probably as bad as not playing internationally at all.
